The spectra of highly ionized iron species between 7 and 9 A have been studied using data obtained at the Princeton Large Torus tokamak under plasma conditions similar to those present in solar and stellar flares. The wavelengths of many iron lines are measured with very high accuracy ( lambda / Delta lambda up to 4 x 104), along with several other lines in species such as He-like Al XII and Mg XI. Theoretical spectra that predict both the wavelength and the intensity of Fe emission lines are compared with the observed spectra and are used to make accurate line identifications. Virtually all the observed iron lines are found to arise from n = 4, 5, and 6 --> 2 transitions in Fe XXI-XXIV, and many lines are identified for the first time. Several transitions are shown to have diagnostic applications, and a detailed analysis of the density sensitivity of Fe XXII lines is presented.
